MM Algorithms for Variance Component Estimation and Selection in Logistic Linear Mixed Model
Liuyi Hu, Wenbin Lu, Jin Zhou +1
Logistic linear mixed model is widely used in experimental designs and genetic analysis with binary traits. Motivated by modern applications, we consider the case with many groups…
Efficient Estimation for Dimension Reduction with Censored Data
Ge Zhao, Yanyuan Ma, Wenbin Lu
We propose a general index model for survival data, which generalizes many commonly used semiparametric survival models and belongs to the framework of dimension reduction. Using a…
On the radiation mechanism of repeating fast radio bursts
Wenbin Lu, Pawan Kumar
Recent observations show that fast radio bursts (FRBs) are energetic but probably non-catastrophic events occurring at cosmological distances. The properties of their progenitors a…
Radiative interaction between the relativistic jet and optically thick envelope in tidal disruption events
Wenbin Lu, Julian Krolik, Patrick Crumley +1
Reverberation observations have uncovered an Fe Kα fluorescence line in the tidal disruption event (TDE) Swift J1644+57 (Kara et al. 2016). The discovery paper used the lag spectru…
Probing motion of fast radio burst sources by timing strongly lensed repeaters
Liang Dai, Wenbin Lu
Given the possible repetitive nature of fast radio bursts (FRBs), their cosmological origin, and their high occurrence, detection of strongly lensed sources due to intervening gala…
Fast radio burst source properties and curvature radiation model
Pawan Kumar, Wenbin Lu, Mukul Bhattacharya
We use the observed properties of fast radio bursts (FRBs) and a number of general physical considerations to provide a broad-brush model for the physical properties of FRB sources…
Stellar disruption events support the existence of the black hole event horizon
Wenbin Lu, Pawan Kumar, Ramesh Narayan
Many black hole (BH) candidates have been discovered in X-ray binaries and in the nuclei of galaxies. The prediction of Einstein's general relativity is that BHs have an event hori…
Thermal and non-thermal emission from the cocoon of a gamma-ray burst jet
Fabio De Colle, Wenbin Lu, Pawan Kumar +2
We present hydrodynamic simulations of the hot cocoon produced when a relativistic jet passes through the gamma-ray burst (GRB) progenitor star and its environment, and we compute…
